Can't see Einstein photo from tutorial 2 but in CMS it is there

I followed tutorial 2 and uploaded a photo of Einstein but I can't see it on the public site. The DIV is just empty <div class="staffphoto"></div>
In CMS view I can see it (in the article and in the asset folder).

The only change I made is to rename photo to Foto.
In StaffPage.ss
$Foto.SetWidth(150)

I got it. After a look in the DB I saw that the relation to the photo wasn't in the live version. I saved and published the page and it gets displayed.
I thought uploading the picture is sufficient and didn't know to publish the article again.
